Embodiment Construction
[0031] The present invention generally comprises a method for generating a dimensional map of the surface of an object, and analyzing the dimensional data to examine the object in useful ways. Referring to FIG. 1, the method involves providing a pair of projectors 11, each of the projectors directed to project a pattern of lines on an object 9. The type of projector utilized may be a conventional type or a digital type. The projectors are spaced apart to illuminate differing aspects of the object. A digital camera 10 is directed at the object 9 to acquire images of the object, and the configuration of the projected patterns on the surface of the object. The images are fed to computer 17 which processes the images to generate a dimensional map that numerically describes the contours, edges, openings, and surface features of the object 9. A range finder 19 is also directed toward the object to obtain at least one absolute measurement of the distance of the apparatus to the object, upo...
